Enzymes were of interest to me because even though I️ had heard of enzymes often in my life, I never knew exactly what they were. However, now I know that enzymes act as catalysts for chemical reactions that occur within a body. Enzymes act upon molecules called substrates, and they bind with the substrates through induced fit. In other words, enzymes are specific shapes for each different shape of substrate. Therefore, enzymes can only act upon one type of substrate: the one they were made for (i.e. lactase has the exact shape for lactose, so lactase can only bind with lactose).
